A privilege escalation vulnerability exists in the Duo Authentication for Windows Logon and RDP implementation. This vulnerability could allow an authenticated local attacker to overwrite files in privileged directories.

The Windows Logon installer prior to 4.1.2 did not properly validate file installation paths. This allows an attacker with local user privileges to coerce the installer to write to arbitrary privileged directories. If successful, an attacker can manipulate files used by Windows Logon, cause Denial of Service (DoS) by deleting file(s), or replace system files to potentially achieve elevation of privileges. Note that this can only exploitable during new installations while the installer is running
